, IDENK'MIXERQ a v The invention relates to; motor-driven drmk-nnxers and its Ob ect s to provide a" device or" this'typef in which the agitating etficiencyzis increased-to expedite'a thorough' blending of the constituents of a drink. This-application is; a division of Serial No. 505,986 filed by Vine. October 7 Q1921 for.

improvements 'indrink mixers. V 3 The inventlon consists in: the several novel features hereinafter set forth and more par-T ticularly definedby claims at the conclusion h8I60f.f:

commonprao tainer or Vessel generally known as a shaker. In practice, thesemotors attain-a high speed, ranging from 5000 to 12,000 revolutionsrper minute. Heretofore; it has been customary to ose a container of circular. l cross-section; In some instances, small protuberances have 'beenforn'ied in the wall of i. V the receptacle to control" or retard thedrink constituents. Thehigh speed ofthe agita- I tor when directly'drive'n by anele'ctri'c mo- .tor,"causes the material to rotatem the container to produce a vortex and to bank-up th sides of the vessel; In these containers,

their agitating eifici'enc'y is lessened by'rapid rotation of the material with theagitator. A desideratum and practical necessity? in drink mixers'is that. the receptacle should have an open top' sothat the service will not be retarded by the necessity of removing and replacing a cover on the container; That-is,

it is desira'ble'to avoid any retarding of'the service by minimizing the steps necessary to a each complete cycle of ,operationan the min-j ingot a drink;andrconsequently, 1t 1s deslraI- V ble to use theopen-toppe'd receptacle into' V which the constituents ofa drink'mayub'e quickly placed andwhich can-be readily and;

easily"placed into its operative position around the agitator. In practiceyl have discovered, .that, the

high speed agitator ina'container which is, polygonal in cross-section or of polyhed'ral form Will act to project the material into.'

The container comprises a bottom 23 and vertical walls 24 joined to the base so as to form 'a' mixingchamher which is approximately rectangular in cross-section. The size and cross-sectional shape of the container; isfsuch that the angles therein will form substantially vertical pockets which aresufiiciently close to the axis of rotation to deflect and act on nearly'all the material which is swirled by the agitator, andto v yieldingly retard the material adjacent the V which the sides aresomewhat elongated to V the: materialto hesplashed through an open have an agitating effect upon themateriai,
